Configuring Tableau and ODBC
Hello All,
In this blog we will see how we can
configure Tableau and ODBC on your system.
Tableau is the most popular data
visualization tool which is used widely to visualize the data. You can discover
and share the insights that can change the business value.
Data visualization is a tool used by
all data scientists which help them communicate with their end-users or
clients. The result of all the data interpretation is not immediately coherent
to the users who do not directly deal with the data. Data visualization acts
like that connectivity point and makes users appreciate the occurrence of the
data analysis. And, Tableau is one of the best Data visualization
software/tools which is used by every other business now.
Tableau is a visual analytics program
modifying the way we use data to solve problems by enabling oneself and
businesses to make the most of their data.
Tableau can perform below tasks.
1. Tracking budgeting expense
2. Sales data analysis
3. User density monitoring
4. Categorizing and sub-categorizing data
5. Consumer segmenting
We will go through all the steps to
configure it with your Kerberos and your Hadoop cluster. Once its connected and
configured properly you will be able to visualize the table data in Tableau
which will help you to analyse your data so that you can take outcome of it.
Purpose:
This
Page depicts the Process of Configuring Tableau and ODBC on the System.
Process:
Step 1:
Install ODBC data sources 64 Bit on your system.
Step 2:
Install Tableau
Step 3:
Install MIT Kerberos on your system.
Step 4:
Create a directory in your C folder For example as Temp1
Step 5:
Open System environmental variables. " Right click on My PC→
properties→ Advanced system settings →Environmental
variables→System variables→
New→Name:KRB5CCNAME, Value:
C:\Temp_1\krb5cache"
Step 6: Go to C:\ProgramData\MIT\Kerberos5 and insert the below
content itno krb5 file. (you can take this from any of you server krb5.conf
file)
[libdefaults]
renew_lifetime = 7d
forwardable = true
default_realm = ADS.<DOMAIN>.COM
ticket_lifetime = 24h
dns_lookup_realm = false
dns_lookup_kdc = false
default_ccache_name = /tmp/krb5cc_%{uid}
#default_tgs_enctypes = aes des3-cbc-sha1 rc4 des-cbc-md5
#default_tkt_enctypes = aes des3-cbc-sha1 rc4 des-cbc-md5
[domain_realm]
.connected.company.com = ADS.<DOMAIN>.COM
[logging]
default = FILE:/var/log/krb5kdc.log
admin_server = FILE:/var/log/kadmind.log
kdc = FILE:/var/log/krb5kdc.log
[realms]
ADS.<DOMAIN>.COM = {
admin_server = ads.azure.company.com
kdc = ads.azure.company.com
}
Step 7:
Restart the system
Step 8:
Open MIT Kerberos and generate ticket using your credentials.
Once
you get the ticket then go to C:\Temp_1 and you should have krb5cache file in
it.
Step 9: Open
ODBC and go to system DNS and select sample
Hortonworks and configure and fill the details
Step 10:
Click on HTT Options and add the HTTP path as below
Step 11:
Click on SSL options and fill the details as shown below
Step 12:
Click on advanced options and select native query.Click on test →
Once test is successful
click
on ok as shown below.
Step 13:
Open Tableau→Click on more and search for odbc
Step 14:
Select ODBC and select DSN and in the drop down choose the ODBC
connection which we created on ODBC. Click on
connect. You will be able to connect to tableau
thank you!!!
let us know in comment section if you face any issue while configuring it.
